Curtis Lopez is charged with the murder of Jane McQuain and William McQuain, pictured.
Details about the murders of 51-year-old mother Jane McQuain and her 11-year-old son William McQuain were released Thursday in charging documents against estranged husband and step-father Curtis Lopez, according to NBC Washington.
Investigators say Jane McQuain was asleep when she was stabbed by Lopez through a blanket on September 30, before being bludgeoned with a weight. Both the knife and the weight were found by police in her condo in Germantown, Maryland.
William McQuain was last seen alive with Lopez on a security camera at a storage facility. The charging documents allege that Lopez retrieved a baseball bat from a storage unit owned by McQuain. Lopez is said to have led the boy into the woods before using the bat to kill him, leaving the bat at the scene of the murder.
Lopez has been in custody in North Carolina since Oct. 13, after police tracked him down when his girlfriend crashed Jane McQuain's car. He was extradited to Maryland on Wednesday.
A Rockville District Court ruled that Lopez would continue to be held without bond. He will next appear in court Dec. 2.
